Abstract

In a vertical type of double disc surface grinding machine, an object of this invention is to enable simple adjustment of a parallelism between a grinding surface of a lower grinding wheel and a work end face clamped by a clamping jig of a rotary table, even when a grinding wheel spindle axis is disordered. The vertical type of double disc surface grinding machine is equipped with a pair of grinding wheels 2 & 3 opposing each other in vertical direction and fixed to a pair of vertical grinding wheels 4 & 5 and a rotary table 15 holding a work W and supplying it to a grinding position A1 located between the grinding wheels 2 & 3, and provided on the rotary table 15 with a work clamping jig 17 including a rotary shaft 63 which clamps the work W at a specified position and makes it spin itself. The table 15 and a bed 14 supporting its drive mechanism are supported by plural supporting legs 12 adjustable in their heights, so that front-to-back and right-to-left inclination angles can be adjusted in relation to horizontal level, and the supporting legs 12 are installed on a slide bed 11 slidable in horizontal direction.
